Poison dependency need to be overriden

[Deleted user]

I get an error because the Poison in my mix.lock is a different version than the one required by Chartkick. I have tried multiple things like unlocking the dependency and still not luck.

  chartkick (version 0.0.2) requires ~> 1.5
  mix.lock specifies 3.1.0

** (Mix) Hex dependency resolution failed, change the version requirements of your dependencies or unlock them (by using mix deps.update or mix deps.unlock). If you are unable to resolve the conflicts you can try overriding with {:dependency, "~> 1.0", override: true}```
